Question

use the properties of triangle to find the unknown angle​

Answer 1

Answer:

122

Step-by-step explanation:

2(180-x)=116

180 -x =58

x=180 -58 = 122

Answer 2

Answer

x = 122°

Step by step explanation

x = Angle A + Angle B ( exterior angle property)

AngleA,

180° - 116°

64°

AngleB and Angle C,

180° - 64°

116°

AngleB = AngleC( two equal sides)

AngleB = Angle C,

116°/2

58°

AngleC+ x = 180° ( straight angle)

58°+ x = 180°

x,

180° - 58°

122°
